Abstract
|
|
|
Bacterial diversities in the guts of sea cucumbers (Apostichopus japonicus) and shrimps (Litopenaeus vannamei)
were investigated using barcoded or tag-encoded 454 pyrosequencing of 16S rRNA genes. In sea cucumbers, most
of sequences were related to two genera, the genus Propionigenium in the phylum Fusobacteria and an unclassified
genus in the family Flavobacteriaceae of phylum Bacteroidetes. Shrimps showed various kinds of genera including
Lactococcus, Leuconostoc, Prochlorococcus, and Vibrio as well as the unclassified genera in the families,
Flavobacteriaceae, Rhodobacteraceae, Desulfobulbaceae, and Helicobacteraceae and in the order Mycoplasmatales.
Unclassified genera containing environmental sequences only are more than half of genera from sea cucumbers and
shrimps. Sea cucumbers and shrimps could be unexplored sources of novel microbes and the bacterial diversity of
them was revealed by high throughput 454 pyrosequencing
